Without the stellar performances from Patrick Bauchau and James Frain, "Eye For An Eye" would probably end up on the pile of Burn Notice episodes which all look vaguely familiar. There's nothing about the plot that is any different than the show's typical bag of tricks, but their characters, Lucien and James, respectively, are pretty compelling characters.
On the one hand, you have Lucien, the old Romanian war criminal bomb maker, who spins tale after tale in a rather agreeable manner. He's actually likable, despite his profession, and as we see his reaction to what may happen to his daughter, we kind of feel sorry for him, especially when his buddy kills him instead of saving him.
On the other, there is James Forte, the rich guy who oozes sleaziness. We learn that he left his business partner to rot in prison and stole his wife, sealing the deal. For all the hatred the audience is supposed to have towards him, he really doesn't have the cunning of a top-class criminal and Jesse, Michael, and Fi take him down with few hitches.
Burn Notice works best when there are colorful personalities, whether it's the villains or one of Michael's personas. "Eye For an Eye" has two good villains and a psycho character from Michael, combining to make an entertaining episode.
Score: 8.9/10
